I had activated DND serivce on my no. 9313555756 since April 09, but still I am receiving calls and sms from telemarketing companies.

I have also lodged a complaint with the Premium Coustomer Care Desk of the company where they said that this problem will be sorted out in 15 days bt today it has been 20 days nthng has been done.
On Contacting again with Customer Care they said that your complaint has been forwarded to the higher authorities and they have checked that these company have not actually called.

They are asking me to give such a number and the contents of the company….
Bit I dont think that they are going to do anything.

So please help me out.
